We used to eat there every time we stayed at WL, which was 5 or 6 stays and it was usually 2 or 3 dinners/breakfasts a stay. We knew exactly what to expect but the last meal was terrible, mainly due to the poor service we received. I don't care if it's the start of the night or the end of the night. If we ask for a simple cup of coffee, then I expect to get a simple cup of coffee without being told that it's too much trouble to brew a new pot.
A couple of questions for you...well, one question and a few comments...
I'm not saying that it's the case, but maybe, food-wise, they were having an off night. If you've enjoyed it before...it is possible that one night, things could be off and if you would have gone the next night, things may have been enjoyable.
Second, I'm sure if you would have let the waitstaff know that you were just there to eat, not there for the antics, they may have respected your wishes and let you eat in peace...I'm not saying that the rest of the restaurant wouldn't have been boisterous, but at least you maybe could have had a quieter meal, if you'd maybe asked for it. I know they do this for character meals...if you seem less than interested in meeting the characters, they stop by maybe, but more than likely leave you quickly.
My question is, if you wanted the coffee and the waiter didn't want to bring it to you, for whatever reason that may be...why didn't you ask to speak with the manager about the situation? That way, the problem would have been brought up to their attention and something maybe could have been done about it...like you maybe would have gotten coffee? I'm not one who complains at restaurants, but if I believe something is wrong with the way I'm treated (which doesn't happen often), I will let the manager know about it.
I'm sorry you feel that this restaurant isn't up to snuff for your family anymore. I enjoy it for what it is...a more fun sit-down meal....nothing more, and nothing less. But not every meal is for every one...personally, I have no real desire to go to the California Grill, despite the fact that it's one of the premiere restaurants on property...so to each his own. It just seems like you're basing your decision not to go back based off of one meal...maybe by trying it again, you may end up finding out it is still an enjoyable meal.
